A manhunt is underway in a remote area of Teton County, Wyo., in connection with the Canyon County triple murder.

A car believed to have been driven by Gerald "Mike" Bullinger was found abandoned in a campground northwest of Moran, Wyoming. The white, 2007 Ford Focus is registered to one of the murder victims.

Authorities say it had been parked there for about three weeks, but believe Bullinger is still in the area.

Agencies involved in the search include FBI, US Marshals Service, Teton County Sheriff, National Park Service, Forest Service and Wyoming Fish and Game.

The Bridger-Teton National Forest has issued a temporary area closure to facilitate law enforcement operations and for public safety. Effective immediately, Pacific Creek campground is closed. The Lava Creek, Box Creek and Clear Creek Trails, as well as all the area around Enos Lake in the Teton Wilderness Area are closed are closed as well.

In Grand Teton National Park, the Pilgrim Creek Road is temporarily closed.

Visitors are encouraged to contact the Blackrock Ranger Station at 307-543-3900 for the latest on closures as the situation could change depending on the search.

“Our primary goal is to keep the residents and visitors safe," said Lieutenant Carr with the Teton County Sheriff’s office.

The warrant for Bullinger charges him with failure to report the deaths of three people and he is considered a person of interest in those deaths. He's also considered armed and dangerous.
